in the training of Naruto make Shikamaru give Naruto a dose of reality and turn him into a serious shinobi ,who understands that teammate like sakura should not physically abuse him
Teach him the shadow clone jutsu memory transfer aspect and force him to send hundreds of his clones to read every book in the library and study everything he should have when he was in the academy.
Have him master everything from the academy before you teach him anything else.
Até faz sentido o que vc tá escrevendo, mas lembre que isso não é um passo a passo pra deixar o mundo de naruto mais fácil, é sim uma história se continuar assim vai virar um slice of life
